Celebrities bond through life in a surf shack and ski lodge and are exposed to the ocean and mountains on a daily basis, experience being at the mercy of the weather and navigate through the trials of tribulations of experiencing a lifestyle far different to living in the city.

Cheng Xiao is also in both shows, evidently still high from the experience of bombing down the slope in an indoor ski resort during the filming of the penultimate episode of One More Try.
It’s not so much the format of the shows that shares commonalities, but rather the sports - the language of boardsports are all interconnected and the joy derived from riding is emphasized in both shows.

FL travels to a different world through technology. ML appears to be the villain, and it takes time for the FL to warm to him/fall in love with him. FLs are quirky and fun.

Similar vibe, FL travels to a game vs. into a drama and must beat the system. Similar setting and fun, fast paced plot.

Similar vibes and relationship between the main characters. Both shows start off sweet and funny then take a turn into heavier court politics and assassination attempts, with a final happy ending.
